What is Castor?

During his MD, our founder Derk Arts, identified a major problem in medical research.

Due to the unavailability of affordable, easy to use data capture tools, researchers were deviating to non-compliant alternatives that reduce data quality, security, and reusability.

He invented Castor which makes compliant data capture effortless and affordable for researchers across the globe. Castor is an Electronic Data Capture cloud-based software, which is used for the collection of clinical data.

As a team, our goal is to make medical research faster and smarter.
